Summary
A compact, brushless 20V cordless 4½in angle grinder delivering solid on-site performance with quick-guard adjustment and a robust DeWalt build.
Findings
From the first on-site use, the balance and low fatigue design impressed, with the brushless motor delivering steady torque to 125mm discs for metalworking tasks. The tool feels responsive and maintains control under load, making light grinding, cutting, and finishing manageable without a mains supply. The tool-free guard adjustment and easy orientation change enable rapid setup for different jobs, while the spindle lock makes disc changes quick and safe. Being cordless removes trip hazards from cables and is particularly handy in tight spaces or overhead work, though you'll want a capable 20V XR battery for a full day's work to keep performance consistent. Build quality feels solid: a robust metal gearbox housing and rugged plastics stand up to daily trade use, and the grip remains comfortable and secure during extended sessions. As a bare tool, it's essential to factor in the battery and charger separately, which adds to the initial outlay. Overall, the tool offers dependable speed stability, durability, and convenient cordless operation that suits professional on-site needs.
